Specification of Letters Patent.

Patented July 16, 1918.

Application filed May 22, 1918. 7 Serial No. 236,046.

have invented new and useful Improvements in Rail-Joints, of which the following is a specification.

This invention relates to rail-joints, and the main object of the sameis the provision of a simple, efficient and comparatively inexpensive construction by which to connect and clamp together the extremities of track rai s.

Another object of the invention is the provision of a construction having parts so made and arranged that the rail ends may beconnected and clamped together without use of bolts and nuts, there being also kept in view in this connection the provision of parts so simple in design that they can be assembled and applied without difficulty or error by unskilled labor.

With these objects and others in view, the invention resides in the details of construction and in the arrangement and combination of parts hereinafter described, defined in'the claims, and set forth in the accompanying drawings, forming a part of this specification; it being understood that changes and alterations in the precise embodiment of the invention herein disclosed, may be made, to which changes and alterations the inventors are entitled, provided the same are effected within the scope of what is claimed.

In the accompanying drawings :Figure 1 is a View in perspective, showing how theparts are assembled to connect two rail extremities, which arehere illustrated in dotted outline.

Fig. 2 is a' fragmental horizontal cross sectional view through the parts and connected rail ends Fig. 3 is a fragmental top plan View.

Fig. 4 is a fragmental vertical sectional view taken in the direction of the line 4-4 of Fig. 3.

Fig. 5 is a perspective view of the locking 1n. P With more particular reference to the ac companying drawings, the numerals 10 and 11 denote a pair of longitudinal splice-bars which are formed to fit flat against the opposite sides of the webs 12 of the connected rail extremities, the top and bottom longitudinal edges 13 and 14 of these bars being chamfered to lc'onform to the heads 15 and base flanges 16, respectively, of the rails.

Formed integral with each splice-bar, intermediate its length, is an offset foot portion 17, which corresponds with the base flanges of the rails in order, when set in between the ends of two rail extremities,'to be in alinement with the same.

Also formed integral with each splicebar is an offset vertically extending enlargement or abutment 18 which rises above the top edges 13, at right angles thereto, far

their feet 17 inserted between the extremities of the ends, the said enlargements will fit between the extremities of the rails so as to comprise an alined bridge therebetween, the inner faces 20 of the same abutting against each other.

In each of these vertical enlargements, intermediate its length, there is provided a vertical dovetailed recess 21, so that when the parts are assembled with the confronting faces 20 abutting against each other, the adjacent angled projections 22, taken together, form a V-shaped rib or lug, the apex of which lies in the direction of the length of the track-rails. Owing to the dovetailed recesses, there are two such V- shaped ribs, which confront each other.

To look the assembled parts together with the rail extremities securely engaged and clamped therebetween, we provide a clamping pin 23 to fit snugly in the dovetailed rethe base flanges and heads thereof, an offset vertical enlargement integral with the inner side of each bar, said enlargements confronting each other and fitting between the rail extremities and comprising a bridge therebetween, a dovetailederecess in each enlargement vertically therein, and means seated in said dovetailed recesses whereby t inter-lock the splice-bars together. i,

.2.-In a rail-joint, a pair of splice-bars formed to lie fiat against the webs of rail extremities, one bar on each side thereof'between the base flanges and rail heads, each bar being formed intermediate its length on its inner side with an offset vertical enlargement to fit between the rail extremities, said enlargements together comprising a bridge between said extremities, each of said enlargements being provided with a dovetailed recess vertically thereof, a clamping pin inserted partly in each recess to lock said plates together, the head of said clamping pin being recessed in the top ends of said enlargements to lie flush therewith.

In testimony whereof we have signed our names to this specification.
